AC question
I took my '73 Omega to the mechanic that works on my other cars and asked him to advise about getting my AC back up and running. Now they don't specialize in AC so I'm not sure if that is the issue, but they said that since my system has been 'open' for quite some time, they would not recommend just putting on a new compressor (which was locked up), as there is probably contamination in the system that will ruin the new compressor.
They are recommending that I replace pretty much the entire system with me purchasing the following items and bringing it all back for them to install:
Compressor
Drier
Condenser
Hoses
Evaporator
Now my hoses were cut while the car sat for 10 years on the side of the previous owners garage, then I've been driving it around about 600 miles over the past two years I've owned it, so would the entire system be contaminated?
They mentioned it might be possible to flush out the system and just replace the compressor but they don't have the means to perform that function. They also suggested that I might first try a mechanic that specializes in AC.
Any suggestions on which way I should go?

Are you converting it to R-134a? If so, you'll need new (or modified) expansion valve and POA valve. A parallel-flow condenser is typically suggested for 134a as well.
I converted my '73 Firebird (T/A clone) to R-134a last year. I used a Sanden compressor, but painted it black so that it does not stand out so much. New condenser, POA and expansion valves, new hoses, and new drier. I removed the original evaporator, flushed it, and had a local radiator shop pressure test it for me.
Classic Auto Air provided most of the parts, and good advice as well.
